What are the basic functions of a tourism big data platform?

Personally, I think that the tourism big data platform is to solve the problem that the managers of scenic spots or cities and counties can understand the tourist destinations more objectively, in other words, it is to solve: where people come from and where people go. Tourism big data platform is a very comprehensive platform. First, it must have sufficient data sources, such as ticket data, UnionPay data, mobile phone operator data, hotel accommodation data, highway car data, parking data and so on. Secondly, we should have the function of data analysis, and make full analysis by using the existing data, such as the source of tourists, the age of tourists, the gender of tourists, the consumption area, the consumption capacity, the stay time, the tour trajectory, etc. Third, we should have the function of presenting the analysis results in real time. Each data source is different, the data update time is different, and the data update time is different. At present, I understand that some places' tourism big data platforms use analog data, that is, they are presented after manual input, and the real ability of big data cannot be withdrawn.
